The CALIPSO collaborative volcano monitoring system on the Caribbean island of Montserrat includes observations strain at depths ∼200 m using Sacks‐Evertson strainmeters. Strain data for March 2004 explosion Soufrière Hills Volcano are characterized by large, roughly equal but opposite polarity changes two near sites and much smaller a more distant site. amplitudes eliminate spherical pressure (Mogi‐type) source as sole contributor. initial followed recoveries, with differing relative...
Very‐long‐period (VLP) pulses with period of 6–7s, displaying similar waveforms, were identified in 1998 from broadband seismographs around the summit crater. These accompanied most multiphase (MP) earthquakes, a type long‐period event locally defined at Merapi Volcano. Source mechanisms for several VLP examined by applying moment tensor inversion to waveform data. Solutions consistent crack striking ∼70° and dipping ∼50° SW, 100m under active dome, suggest pressurized gas transport...
Purpose This study aims to investigate the factors that influence use of e-government services among male and female samples, aiming at gaining a deeper understanding how promote digital inclusion maximize benefits digitalization. Design/methodology/approach uses binomial logistic regression modeling on two data sets: nationwide survey individual level 8,854 usable samples conducted in 2019 village potential statistics. Findings The indicates low adoption both males females. statistical...
Abstract Since 1995 the eruption of andesitic Soufrière Hills Volcano (SHV), Montserrat, has been studied in substantial detail. As an important contribution to this effort, Seismic Experiment with Airgunsource-Caribbean Andesitic Lava Island Precision Seismo-geodetic Observatory (SEA-CALIPSO) experiment was devised image arc crust underlying and, if possible, magma system at SHV using tomography and reflection seismology. Field operations were carried out October–December 2007, deployment...
